Squashed commit of the following:
fs/spiffs: Fix last compilation issue. Now compiles without error. It is still not quite ready for testing as there is additional code review that must be be performed. It is now marked as EXPERIMENTAL so that it can be brought onto the master branch with little risk.
fs/spiffs: Remove some dead code.
fs/spiffs: Weak start of analysis of spiffs_nucleus.c. Renamed to spiffs_core.c
fs/spiffs: Rename spiffs_nucleus.c to spiffs_core.c
fs/spiffs: Remove spiffs_config.h. All configuration settings are now available in the SPIFFS Kconfig options.
fs/spiffs: Finished review, update, and repartitioning of spiffs_check.c. Added spiffs_check.h.
fs/spiffs: Finished review, update, and repartitioning of spiffs_cache.c. Added spiffs_cache.h.
fs/spiffs: Clean up some defines used in debug output statements.
fs/spiffs: Finished review, update, and repartitioning of spiffs_gc.c. Added spiffs_gc.h.
fs/spiffs: Now that VFS interface is completed, I have begun the long march of repartitioning the remaining functionality, reviewing logic, identifying dead code, and cleaning up loose ends.
fs/spiffs: Initial integration of MTD interface, replacing the SPIFFS native flash interface. Lots of open issues such as the use of pages vs. blocks vs. erase blocks and units of addresses, offsets, and lengths that are passed in function calls. Remove SPIFFS_USE_MAGIC support. That option (which default to OFF anyway), wrote a magic value at the beginning of every sector and support verifiable identification of the file system. It was not being and used and removing it makes life simpler.
fs/spiffs: Remove semaphore lock on the file object structure. Ultimately, the file access must modify the volume and access the volume structue which also has a exclusivity lock. So use of the volume lock alone should be sufficient.
Integrated the SPIFFS rename logic into the NuttX VFS. Removed non-standard application calls or convert them to IOCTL commands. These were converted to IOCTL commands: (1) integrity check, (2) garbage collection, and (3) format flash. These were removed: (1) Integrity check callback. These provided a lot of good information about the state of the file system, but such callbacks are not compatible with a POSIX compliant file system. (2) Index maps. The index maps were a performance improvement feature. The user could provide the memory and request that a region of a a file use that memory for improved lookup performance when accessing parts of the file. The fallback is the less performance lookup by traversing the FLASH memory. (3) Removed the quick garbage collection interface (the code is still used internally). Only the full garbage collection is available to the user application via IOCTL.
configs/sim/spiffs: A simulator configuration to use for testing SPIFFS.
fs/spiffs: Integrate SPIFFS logic into NuttX VFS bind() and unbind() methods.
fs/mount/fs_mount.c: Add SPIFFS to the list of drivers that require MTD vs block drivers.
fs/spiffs: Trivial changes, mostly from analysis of how to integrate the rename() VFS method.
fs/spiffs: Connect NuttX VFS unlink method to the SPIFFS_remove() function. Lots of name-changing.
fs/spiffs: Remove non-standard errno support. Remove bogus SPIFFS_LOCK() and SPIFFS_UNLOCK() macros.
fs/spiffs: Add NuttX VFS implementation for statfs() method. Clean up some of the accumulating compilation problems.
fs/spiffs: Add stat(), truncate() methods. Dummy out unsupport mkdir() and rmdir() methods.
fs/spiffs: Replace some of the custom error numbers with standard error numbers.
fs/spiffs: Hooks read(), write(), fstat(), ioctl(), opendir(), closedir(), rewindif(), and readdir() into the NuttX VFS.
fs/spiffs: Beginning the organization to work with the NuttX VFS. Lots of things are get broken!
fs/spiffs: Add spiffs.c which will be the interface between SPIFFS and NuttX. No very close at present, however.
fs/spiffs: Clean up some compile problems introduced by coding standard changes.
fs/spiffs: A little closer to NuttX coding standard.
fs/spiffs: Ran tools/indent.sh against all files. Closer to NuttX coding standard, but needs a lot more effort to be fully compliant.
fs/spiffs: This commit brings in version 0.3.7 of Peter Anderson's SPIFFS. The initial commit includes the core FS files (with some definitions destributed to their correct header files) and hooks into the build system.
fs/driver and fs/mount: Add mount() support for file systems that require MTD drivers (vs. block drivers).
fs/drivers: Add support for named MTD drivers in the psuedo file system. This will, eventually, allow us to mount file systems that need MTD drivers without having to fake an intervening block driver.
Squashed commit of the following:
net/netlink: Mark netlink support as EXPERIMENTAL.
net/netlink/netlink_sockif.c: Add netlink_getpeername to the socket interface.
net: Add getpeeername() support for netlink sockets.
include/netpacket/netlink.h: Add a few more definitions and structures used at the NetLink interface. Still missing many.
net/netlink: Add basic framework for Netlink socket support.
include/: Add basic Netlink definitions.
include/sys: Remove unused SYS_nnetsocket from syscall.h
Because SYS_nnetsocket is not implemented so far, it should be
removed so that SYS_prctl can work correctly.

sched/clock: Move the implementation of clock() from libs/libc/time to sched/clock. This is necessary because it calls the (now) internal OS function clock_systimer. clock() is now accessed only via a system call in certain configuratins.
libs/libc/wqueue: Replace calls to clock_systimer() with calls to the equivalent clock().

fs/cromfs: Now depends on EXPERIMENTAL because it is not yet verified.
fs/cromfs: This commit brings the CROMFS file system to code complete. Still completely untested. Next steps: Need a tool to generate CROMFS file system images and a test case under apps/
fs/cromfs: Add logic to traverse the in-memory file system nodes.
fs/cromfs: Add initial support for an in-memory, compressed, read-only file system.
net/tcp: Add logic to send probes when SO_KEEPALIVE is enabled.
net/tcp: TCP socket should not have to be connected to configure KeepAlive.
net/: Add a separate configuration to enable/disable KEEPALIVE socket options.
net/tcp: Arguments to TCP keep-alive timing functions probably should be struct timeval as are the times for other time-related socket options.
net/tcp: Fix a backward conditional
net/tcp: Add some more checks and debug output to TCP-protocol socket options.
net/tcp: Cosmetic changes to some alignment.
net/: Adds socket options needed to manage TCP-keepalive and TCP state machine logic to detect if that the remote peer is alive. Still missing the timer poll logic to send the keep-alive probes and the state machine logic to respond to probes.
Squashed commit of the following:
configs: Each board now initializes the touchscreen controller as a normal part of its board bring-up. board_tsc_setup() is gone; the touchscreen controller is now treated like any other on-board device.
Remove all support for BOARDIOC_TSCTEST_SETUP
Move prototype for board_tsc_setup() from include/nuttx/board.h to individual board header files.
fs: Add truncate() support for userfs
fs/unionfs: Add truncate() support to the unionfs
fs/tmpfs: Add ftruncate() support to tmpfs
syscall/: Add system call support for ftruncate()
net/route: Adding ftruncate() support eliminates an issue in file-based routing table management.
fs: Add basic framework to support truncate() and ftruncate(). The infrastructure is complete. Now, however, the actual implementation of ftruncate() will have to be done for each file system.
fs/userfs: This completes coding of the UserFS client and of the UserFS feature in general. This feature is being merged to main now because I believe it is innocuous. It is, however, untesed. The next step will be to develop a test case to verify the feature.
fs/userfs: Completes the request logic for the UserFS client. Still need the logic that receives the responses.
fs/userfs: Completes coding for most of the server side of the user filesystem logic.
fs/userfs: Big design changes, simplications. Use Unix domain local sockets instead of message queues. Easier to transfer big data in local sockets than message queues. Remove character drvier 'factory' it is not necessary.
fs/userfs: Minor reparitioning; volume private info does not need to be held on the OS client side.
libc/userfs: Add some of the server side logic.
fs/userfs: Add some UserFS initialization logic.
fs/userfs: Add frame work for the UserFS proxy. Remove all references to a block driver. There is no block dricer... what was I thinking?
fs/userfs: Add some initialization of the character driver, 'factory' device.
fs/userfs: Rename from fusefs to userfs to that we don't stomp on someone else's cool name.
Add a header file describing the fusefs interface.
There are two issues with it however:
1. Reading from file system on a per packet basis could be slow. I think it probably should have a small, in-memory cache of most frequently used routes for good problem.
2. Currently the delroute logic is disabled due to a problem with the design. NuttX does not currently support truncate(). Therefore, it is not possible to delete entries from the routing table file.
In this current implementation, that leaves the last entry intact at the end of the file. An alternative design might include a tag on each record to indicate if the record is valid or not. That would work but would add complexity to the other routing table functions.
The existing implementation is available for testing purposes only if CONFIG_EXPERIMENTAL=y.
Squashed commit of the following:
net/route: The current delroute design depends on file truncation. However, NuttX does not currently support truncate. Alternative, more complex designs are possible but not implemented. At present the file routing table are otherwise functional but the delroute logic is disabled via CONFIG_EXPERIMENTAL. Enable it only if you plan to fix it.
net/route: Fix some issues with locking routing table files.
net/route: Add partial implementation of delroute for the case where the routing table is in a file.
net/route: Add support for seeking to positions in the routing table.
net/route: Add net_addroute_ipv4/6() using a file-based routing table.
net/route: Add net_foreach_ipv4/4() using a file-based routing table.
net/route: Initial build, configuration, and fs utilies to support routing tables in a file.

[[This is part 1 or several commits]]
We developed a huge Changeset over a year ago to make USB Composite configuration dynamical and be able to instanciate the CDCACM multiple times inside this device. We use this feature to switch between one in normal and up to three CDCACMs in maintenance boot.
The control path starts in “boardctl.c” where the configuration for the device is constructed. There are still a few issues which I’ll ask you to have a look at before this beast can be merged.
1. To be able to construct the data dynamically I have changed some USB-Structs to be packed. Maybe there are additional structs to change (just for completeness – not for current functionality).
2. I’ve added the Macro “COMPILE_TIME_ASSERTION” two times (in usbmsc_desc.c and in cdcacm_desc.c) to stay private. Maybe you’ll find a better place. It’s used to check the size of the structs against the assumptions.
3. I’ve changed the interface for some USB-Functions to receive also the dynamic configuration. Maybe this can be done more elegant.
4. The original NuttX (without the patch) seems to have problems with a Composite device holding a CDCACM and an MSC. The “USB SET CONFIGURATION” request does not to work at all. This makes the test fail under Windows and under Linux. Applying this patch doesn’t change anything – because it only changes the configuration – not the behavior. Maybe you’ll have a look at this problem before applying the patch.
Entropy pool gathers environmental noise from device drivers, user-space, etc., and returns good random numbers, suitable for cryptographic use. Based on entropy pool design from *BSDs and uses BLAKE2Xs algorithm for CSPRNG output.
Patch also adds /dev/urandom support for using entropy pool RNG and new 'getrandom' system call for getting randomness without file-descriptor usage (thus avoiding file-descriptor exhaustion attacks). The 'getrandom' interface is similar as 'getentropy' and 'getrandom' available on OpenBSD and Linux respectively.
